  • Steam generators for steam cleaning equipment usually have a boiler in which a defined amount of water stored and heated after commissioning of the device to a predetermined temperature or a given, prevailing in the boiler steam pressure. Depending on the amount of water that is in the boiler, and depending on the available heating power such devices require a certain heat-up time, which may be five minutes, for example. Only after the heating time has elapsed, the steam cleaning device is ready for operation. When using the steam generator in a steam cleaning device, steam can only be directed to a surface to be cleaned after the end of the heating time. Alternatively, steam can be supplied to a steam iron at the end of the heating time.
